Richiedi l'accesso ai contatti a livello di codice

Dall'aggiornamento a iOS 6 ho notato che il mio codice per aggiungere un contatto alla rubrica dell'iPhone non funziona più. Credo che questo sia un problema relativo all'autorizzazione, poiché Apple ora richiede l'autorizzazione dell'utente prima di accedere ai contatti (correzione questo problema).

Mi aspettavo che l'app chiedesse automaticamente il permesso di accedere ai contatti, come nello screenshot qui sotto, ma non è così. Il tentativo di aggiungere il contatto non riesce con ABAddressBookErrorDomain error 1.

Devo avviare in modo programmatico l'accesso alla finestra di dialogo di richiesta dei contatti? Come si fa?

Come da questa documentazione sul sito di Apple (scorri verso il basso fino a Privacy al centro della pagina), l'accesso alla rubrica deve essere concesso prima di poter accedere a livello di programmazione. Ecco cosa ho finito per fare.

  #import <AddressBookUI/AddressBookUI.h>

  // Request authorization to Address Book
  ABAddressBookRef addressBookRef = ABAddressBookCreateWithOptions(NULL, NULL);

  if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusNotDetermined) {
    ABAddressBookRequestAccessWithCompletion(addressBookRef, ^(bool granted, CFErrorRef error) {
      if (granted) {
          // First time access has been granted, add the contact
          [self _addContactToAddressBook];
      } else {
          // User denied access
          // Display an alert telling user the contact could not be added
      }
    });
  }
  else if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusAuthorized) {
    // The user has previously given access, add the contact
    [self _addContactToAddressBook];
  }
  else {
    // The user has previously denied access
    // Send an alert telling user to change privacy setting in settings app
  }

Aggiornamento per iOS 9 e versioni successive:

Dal sito web di Apple:

Importante

Il framework dell'interfaccia utente della rubrica è obsoleto in iOS 9. Utilizza invece le API definite nel framework ContactsUI. Per saperne di più, vedi ContactsUI

Questo ha fatto il trucco perfetto per me!

Su iOS6, Apple introduce un nuovo controllo della privacy, l'utente può controllare l'accesso al contatto e al calendario da parte di ciascuna app. Quindi, nella parte del codice, è necessario aggiungere un modo per richiedere l'autorizzazione. In iOS5 o versioni precedenti, possiamo sempre chiamare

ABAddressBookRef addressBook = ABAddressBookCreate();

per ottenere la rubrica senza problemi, ma in iOS6, se non hai il permesso, questa chiamata restituirà semplicemente un puntatore vuoto. Ecco perché dobbiamo cambiare il metodo per ottenere ABAddressBookRef.

__block BOOL accessGranted = NO;
if (ABAddressBookRequestAccessWithCompletion != NULL) { // we're on iOS 6
    dispatch_semaphore_t sema = dispatch_semaphore_create(0);
    ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) {
        accessGranted = granted;
        dispatch_semaphore_signal(sema);
    });
    dispatch_semaphore_wait(sema, DISPATCH_TIME_FOREVER);
    dispatch_release(sema);   
}
else { // we're on iOS 5 or older
    accessGranted = YES;
}

if (accessGranted) {
    // Do whatever you want here.
}

Nel codice, il semaforo viene utilizzato per il blocco fino alla risposta, mentre ABAddressBookRequestAccessWithCompletion chiederà l'autorizzazione se l'app non lo ha chiesto prima. Altrimenti seguirà semplicemente le impostazioni in Impostazioni-Privacy-Contatto.

Ha avuto alcuni problemi con yunas codice su iOS6.1 in Xcode5. Con alcuni piccoli adattamenti ha funzionato per me.

Il problema era che ARC in iOS 6 non consentiva dispatch_release(sema);Ecco il codice funzionante. Nota: io uso m_addressbookinvece di addressbookcome ABAddressBookRef!

Se qualcuno ha problemi con addressBook in iOS5, usa

ABAddressBookRef addressBook = ABAddressBookCreate(); 

Invece di

ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL,NULL);

ABAddressBookRequestAccessWithCompletion(ABAddressBookCreateWithOptions(NULL, nil), ^(bool granted, CFErrorRef error) {
        dispatch_async(dispatch_get_main_queue(), ^{
            if (!granted){
                    [[[UIAlertView alloc] initWithTitle:@"Contacts Access Denied"
                                                message:@"This app requires access to your device's Contacts.\n\nPlease enable Contacts access for this app in Settings / Privacy / Contacts"
                                               delegate:nil
                                      cancelButtonTitle:@"Dismiss"
                                      otherButtonTitles:nil] show];
            } else {
                //access authorized
            }
        });
    });

Per aggiungere la descrizione all'avviso utilizzare in InfoPlist.strings.

Swift 3. Non dimenticare di importare i contatti

func requestForContactAccess(completionHandler: @escaping (_ accessGranted: Bool) -> Void) {
    let authorizationStatus = CNContactStore.authorizationStatus(for: CNEntityType.contacts)
    switch authorizationStatus {
    case .authorized:
        completionHandler(true)
    case .denied, .notDetermined:
        self.contactStore.requestAccess(for: CNEntityType.contacts, completionHandler: { (access, accessError) -> Void in
            if access {
                completionHandler(access)
            } else {
                if authorizationStatus == CNAuthorizationStatus.denied {
                    DispatchQueue.main.async(execute: { () -> Void in
                        let message = "\(accessError!.localizedDescription)\n\nPlease allow the app to access your contacts through the Settings."
                        self.showMessage(message: message)
                    })
                }
            }
        })
    default:
        completionHandler(false)
    }
}

Secondo la recente documentazione di sviluppo di Apple su iOS, Apple insiste nell'usare Contact oltre a AddressBook .

CNAuthorizationStatus authorizationStatus = [CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts];
    switch (authorizationStatus) {
        case CNAuthorizationStatusNotDetermined: {

            break;
        }
        case CNAuthorizationStatusRestricted: {

            break;
        }
        case CNAuthorizationStatusDenied:{

            return;
        }
            break;
        case CNAuthorizationStatusAuthorized: {

            break;
        }
    }

Il codice c dell'obiettivo sopra aiuta a trovare l'autorizzazione all'accesso ai contatti meteorologici concessa o meno.

Con iOS 6 devi chiedere il permesso in questo modo
